Additionally, these digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25 mA on all terminal pins for driving larger loads.

These features, combined with an extended temperature range of -40°C to +125°C, make the MCP41HVXX well suited for a broad range of high-voltage and high-temperature applications, including those in the industrial, automotive and audio markets.

Both digital potentiometers are available today for samples and volume production, in 14-pin TSSOP and 20-pin, 5x5 mm QFN packages. The MCP41HV31 is $0.99 each and the MCP41HV51 is $1.09 each, in 5,000-unit quantities.
